Implementations

impl Key

pub fn to_type_order(&self) -> usize

As per cbor spec, map’s key can be a heterogeneous collection of types. That is, some of the keys can be Boolean, other can be numbers etc ..

This function defines the ordering for supported key types. As,

• Key::Bool, sort before every other keys.
• Key::N64, sort after boolean type.
• Key::U64, sort after negative integers.
• Key::F32, sort after positive integers.
• Key::F64, sort after 32-bit floating point numbers.
• Key::Bytes, sort after 64-bit floating point numbers.
• Key::Text, sort after bytes.

Trait Implementations

impl Arbitrary for Key

fn arbitrary(u: &mut Unstructured<'_>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'_>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn shrink(&self) -> Box<dyn Iterator<Item = Self>>

Generate an iterator of derived values which are “smaller” than the original self instance.

impl Clone for Key

fn clone(&self) -> Key

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Key

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromCbor for Key

fn from_cbor(val: Cbor) -> Result<Key>

Convert value from Cbor into type’s value.

impl IntoCbor for Key

fn into_cbor(self) -> Result<Cbor>

Convert implementing type’s value into Cbor.

impl Ord for Key

fn cmp(&self, other: &Key) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Key

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Key

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
